Abstract: PURPOSE:To produce a bent pipe such as a racket frame excellent not only in surface grade but also in physical properties. CONSTITUTION:A mandrel formed by bundling many fine CFRP wire rads is covered with a tube and a carbon fiber hellcally wound layer is formed to the periphery of the tube using a filament winding method and, subsequently, the mandrel is pulled out to form a preform. This preform is received in a lower mold having a cavity formed into a desired bent pipe shape to close the lower mold by an upper mold and a resin is injected in the cavity while pressure is applied to the interior of the tube and the cavity is reduced in pressure to be infiltrated in the helically wound layer to produce a bent pipe such as a racket frame.

Abstract: PURPOSE:To enable even a long pipe to be prepared easily at high productivity, by shaping under leading-in a reinforcing fibrous base material in hose form stored between first and second means for supporting mandrel before the completion of the delivery of total amount of the same base material stored between the second means for supporting mandrel and a shaping means. CONSTITUTION:First and second means 1, 2 for supporting mandrel and a shaping means 3 and a take-off means 4 are arranged in the same axial line, and a single mandrel 5 is inserted through each means. A reinforcing fibrous base material 13 in hose form inserted under fitting to the mandrel 5 is stored at a section A, namely, a space between the second supporting means 2 and the shaping means 3, and the same base material is stored at a section B, namely, a space between the first supporting means 1 and the second supporting means 2. The take-off means 4 is worked and as the base material 13 is delivered to the shaping means 3, it is impregnated with a resin through sprayers 17, 18 and is shaped into a pipe form through a heated mold 16 for shaping. When the base material 3 is stored at the section A is decreased as shaping operation proceeds, the base material 13 stored at the section B is fed into the section A. As is operation is repeatedly executed, an FRP pipe comes out continuously from the take-off means 4.

Abstract: PROBLEM TO BE SOLVED: To manufacture an FRP material having a low facility cost without impairing mechanical characteristics of a molding without dust and noise by forming a folding pattern at least on one side surface of the molding made of a fiber-reinforced composite material. SOLUTION: The FRP material 1 is a lengthy solid flat plate strip-like molding in an entirety, and is used mainly as a reinforcing material of a concrete structure. Here, the material 1 is formed with an interstice pattern made of a layer of a thermosetting resin cured material on a surface of a molding 3 of the FRP material made of reinforcing fibers 3a and a resin cured material 3b. The interstice pattern is formed on a surface of a resin or the like when a woven fabric is press bonded to a resin or the-like having flowability as a casting mold, and, after the resin or the like is cured, the pattern formed on the surface of the resin or the like is formed when the fabric is released. That is, a cloth 2' is laminated and cured on the surface of the molding 3, and the molding 3 is supplied to a job site in this state as it is, then the cloth 2' is released from the molding 3 immediately before execution, and used as the material 1.

Abstract: PROBLEM TO BE SOLVED: To prevent an IC chip from peeling from a substrate film or being disabled, by using an IC sealing frame having at least specified modulus of longitudinal elasticity. SOLUTION: An IC sealing frame 1 is made of FRP including reinforcing fibers 2 extending along the frame and a resin matrix 3. The frame 1 has a modulus of longitudinal elasticity at least 80GPa and size of 5-20mm long, 5-20mm wide and 0.2-1.5mm thick, depending on the size of used IC chip. The reinforcing fibers are high-strength and high-elastic modulus ones e.g. C fibers, an the matrix is a thermosetting resin such as epoxy resin or thermoplastic resin such as nylon resin. Thus, the IC chip in an IC card hardly peels from a substrate film or malfunctions or is disabled due to a large bending stress.

Abstract: PROBLEM TO BE SOLVED: To secure a good adhesion condition and high adhesive strength by forming vents in one backing to be dispersed and sticking both backings together when the residual amount of an adhesive is in a specified range to the initial amount of a solvent in sticking the first and second backings together with a solvent type adhesive. SOLUTION: A structure 1 is composed of a first backing 2, a second backing 3, and an adhesive layer 4 placed between the first backing 2 and the second backing 3. At least in one of the first backing 2 and the second backing 3, for example, in the first backing 2, vents 5 consisting of through holes are formed to be dispersed appropriately. In this way, after a solvent type adhesive being applied, when both backings 2, 3 are stuck to be bonded together, the solvent in the adhesive is released through the vents 5 to bring about a condition in which no solvent is in the adhesive layer 4 after the completion of adhesion, and before the completion of adhesion, an appropriate solvent is made to remain in the adhesive. After the adhesive being applied, the residual amount of the solvent in the adhesive when the sticking of the backings 2, 3 is started is made 10-20wt.% of the initial amount of the solvent.
